Blizzard

A bright, jagged streak flashes from your hand to a point you choose within range and then blossoms into a flurry of snow and ice. Each creature in a 50-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 cold damage on a failed save, or half as much damage on a successful one.

The ice spreads around corners. It snuffs out flaming objects in the area that aren't magical or being carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
